There is a very interesting article in the International Herald Tribune about QR, or quick response codes. It begins with a young woman snapping a picture with her cell phone of QR code on a movie poster and instantly retrieving show times and a review of the film.

From the article:

QR, or quick response, codes are a similar to bar codes except they are square, look a bit like an ink blot and contain much more information. In Japan and South Korea, QR codes are used to link directly to a Web site, as in the case of the subway poster, saving the user the need to type an address on the tiny keypad of the phone. As marketers seek an edge on competitors, QR codes are appearing practically everywhere in Japan.
